Although not all medical professionals consider adrenal fatigue a real syndrome, those doctors who do believe in the validity of the condition note that its symptoms include trouble getting out of bed, problems concentrating or thinking clearly, and difficulty finishing tasks, notes WebMD. Chronic tiredness is an additional symptom.
Although no evidence exists to support the theory of adrenal fatigue, proponents say it is a condition where the adrenal gland loses its functionality when a person experiences mental, physical or emotional distress, reports WebMD. The adrenal fatigue theory suggests that when life becomes stressful, the adrenal glands do not pump out enough hormones, including cortisol, which is a hormone produced by the body to handle stress. The result is adrenal fatigue symptoms.
Detractors of adrenal fatigue theory say that other health issues commonly cause the symptoms of the condition, reports WebMD. Poor diet and sleep habits, depression, and stress at home or work can cause the symptoms purported to be the result of adrenal fatigue syndrome. Fatigue is also a symptom of heart failure, diabetes, arthritis and anemia, among others.
By contrast, adrenal insufficiency is a medical condition diagnosed via blood tests and special adrenal hormones tests, according to Mayo Clinic. Adrenal insufficiency, also known as Addisons disease, causes symptoms of fatigue, body aches, low blood pressure and loss of body hair. Lightheadedness, unexplained weight loss and hyperpigmentation of the skin are additional symptoms.
